1Housing characteristics data were collected between August 2015 and April 2016.
2Total U.S. includes all primary occupied housing units in the 50 states and the District of Columbia. Vacant housing units, seasonal units, second homes, military houses, and group quarters are excluded.
3Total square footage includes all basements, finished or conditioned (heated or cooled) areas of attics, and conditioned garage space that is attached to the home. Unconditioned and unfinished areas in attics and attached garages are excluded. The square footage for some housing units was calculated based on measurements taken by the interviewer. For households responding without the presence of an interviewer, square footage was imputed based on characteristics of the housing unit. See 2015 RECS Square Footage Methodology for full details about data collection and processing.
4When calculating average heated and cooled square footage all housing units are considered, including those that are not heated or cooled.
5Housing units are classified using criteria created by the U.S. Census Bureau based on 2010 Census data. Urbanized areas are densely settled groupings of blocks or tracts with 50,000 or more people, while urban clusters have at least 2,500 but less than 50,000 people. All other areas are rural.
6These climate regions were created by the Building America program, sponsored by the U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy (EERE).
7Households that use propane only for outdoor grilling are excluded from the RECS estimate of households using propane.         
8Rented includes households that occupy their primary housing units without paying rent.

Notes:  Because of rounding, data may not sum to totals.  See RECS Terminology for definition of terms used in these tables.
